.To all whom-it may concern:

Be it known that I, LINDoN W. Barns a Y citizen of theUnited States, residing at C i- C is seated wi cago, in the county of Cook and State of Illinois, have invented certain new andA useful Im rovements in Dredging-Pipe Joints, of which the following is a specification. f

My present invention pertains to improvements in joints for pipes for dredgers and the like, the advantages and construction of which will behereinafter set forth, reference being had to the accompanying drawings `wherein,

Figure 1 is a side elevation, partly in section, of the improved joint;

Fig. 2, a similar view looking at the joint from a differentppint of view, or'at right angles to Fig. 1;-

ig. 3 a longitudinal sectiona view showm the relationyof the parts when one is move( relatively tthe other; Fi View of oncle-'of the lugs orv rackets Fig. 5, a transverse sectional view on the'line 1-1 of Fig. 3, and Figs. 6, 7 and 8, detail views showing a modified ferm of certain features ef the invention.

The object of my resent invention is te provide a combined) universal ball and socket joint for dredger discharge pipes, wherein great latitude of movement is secured, as well as a pipe .possessin an interior practically free from al sharp a utments or an les.

eferring to the accompanying drawings, A indicates one member of the b'all and socket joint which may be termed the socket piece, and B denotes a corres ending memer which is termed the bal. As will be seen more'particularl upon reference to Fig.

portion of the member A is formed upon a circleof a sli htly larger' radius than the, outer curved ace of the member B, so that the member B is free to turn or move within the curved portion of the member A and yet `form a practically closed joint therewith.

To prevent leakage between the parts, iibrous packing or preferably a packing tube t in a groove or channel formed at the mouth of the socket or bell-shaped member A, said tube being inflated through a valve in order to make a ti ht joint with the outer curved face of the ba l memberB. As will be noted upon reference to Figs. 1, 2 and 3 the location or position of the packing ring with res 4ect to he center line of the as to obtain a maximum 3, the interior curve section B is suc 4, a bottom plan angular deviation with a minimum diameter of s here.

ach of the sections A and B is, of course, connected with a section or length of pipe E, as is usual.

To maintain the parts against longitudinal separation and yet to ermit a universal movement, certain devices are employed which w1ll now be described.

The upper or socket section A is, as will benoted upon reference to Figs. 1 and 2, provided with two oppositely-disposed lu s or bosses F preferably formed integral wit the section. These bosses are tapped out and are designed to receive bolts or screws G which pass freelythrough openings in a ring or member H, said ring or member extending around the sectionsat a slight distance therefrom, and bearing onlyagainst the faces vof the lugs F. v y

Extending out from the lower member B are two brackets I, said brackets standing at right angles to the lugs F of the upper section, or, in other Words, being formed on a diameter which is `at right angles to the diameter which would pass threugh'the lu s F. Brackets I, as will be noted more particu arly upon reference to Figs. 1, 4 and 5, are rovided with a rectangular slot or recess which passestherethrough, and-which is designed to receive the lower ends of the wedge-shaped `ends thereof, as is best illustrated in Figs. 1

and 3. at their upper ends with openings into which reject the rounded portion ofD the ends of bolts or screws K which, as will be seen in lligs. 2 and 3, are screwed through the ring the upper section with the ends of the bolts or screws K acting as pivots.

Movement of section A in a reverse direction, or in a direction at ri ht angles to that just described, will take p ace by reason of the section A turnin with the bolts or screws G in the member This position is illustrated in Fig. 3. Of course, 1f the member A and its attached ipe are held against movement, then member B with the arms J and the ring secured thereto, will b'e moved about the screws or bolts G and the same result accomplished. It will of course be seen that The members or arms J are provided Thus the rin will be free to turn with scribed will take place with a genera movement of the arts ;vthat is to say, the ring swinging on t 1e bolts or screws J ,and the u per sectlon A swin ing independently of t ie rin vor turning in t e ring as above noted.

' screw G passes, is made oblong so that there may bev a slight de ree of torsional movement of the parts. Thlsnot onljT facilitates the coupling up ofthe members, butis also of service in 'preventing the parts from being undul strained when in use.

In' i s. 6, 7- and 8 there is shown a slightly modifie( form of construction, wherein the wedge blocks'or members J, corresponding to the members J of the construction above set forth, are lprovided with an oblon slot or opening whic permits of the torsiona moyement just referred to. The screwsmor bolts which pass through the ring and into the lug of the upper member are, in this instance, as

. members but by the encircling members and v lshown in Fig. 8, screwed into the ring, with the inner end of the bolt made cylindrical and fitting within and free to turn in a socket formed in the lugs u on the upper section.

. It will be noted wit this construction that the iour bolts or screws which go to connect theparts together are all made secure 4to the ring, "whereas in the construction shown in 1 to 5 inclusive, but one pair of screws, namely those connecting the ring and the wedge-shaped arms J, are secured to the ring, the ring being free. to turn upon'the oppositely-dlsposed bolts or screws G.

It is to .be noted that in the construction above described the ball and socket surfaces do not necessarily touch, and that resistance to longitudinal motion is offered not by these pivots.

The brackets I and the members or arms J andvJ may be termed 'a yoke.

It is immaterial whether the bolts or lscrews G are threaded into the members F and are loose uplon the ring, as shown in Fig. 1, orjvhether t e screws, as K, are threaded in the ring and have their loose bearing in the ends of the arms or yokes, as shown in Figs. .2 and 3.- A reversal of this arrangement, of course, falls within the sco e of my invention, and is a mere mechanica change, not involving invention. It is likewise immaterial whether or not the ring be of such size as topass within the arms of the yoke, and the trunnions extend outwardly therefrom, or the ring be made of a size to pass outside of the arms of the yoke and the trunnions extend inwardly therefrom and are pivotally mounted in the oke. e From a Amere inspection o the drawings it will be noted that the axis of the trunnions of the rino' substantially includes the center of the ba -section B.

Having thus described my invention, what I claim is:
